I have it install quite sometime ago. But after getting queries about it from several friends of mine, then only I realize that it is missing from my posting.
The work was done on February last year and yes, I can feel the difference immediately after having it installed...

At this moment, it is impossible to get Elantra/Avante X20 extractor in the market but the shop manage to find an alternative to it. They tried Matrix 1.8 extractor and walla.. it fit nicely to the mounting. However, minor adjustment need to be done to the end flange connected to the exhaust mid section as the flange orientation is slightly different.. no big deal.

New hole created for the O2 sensor as the ready made connection is being plugged and you can also see the bottom part has been cut in order to adjust the end flange orientation.

Next is the muffler.

The installation is quite fast, cut, remove and install.
After everything is completed, I have the ECU reset before I start the engine.
Today we gathered at the exhaust shop in Sunway to install the extractor to 3 of the X20. 10 members turn up this morning (8 ~ Elantra and 2 ~ Accent). Apart from the installation.. we do enjoy our time together, sharing infos and stick around until all the installation is completed...
